We ask the question, “Is there Wi-Fi?” more often than anything else. A recent survey on Wi-Fi trends concludes that 71% of travelers usually avoid hotels that charge for a Wi-Fi connection.
The bottom line is that Wi-Fi has become an indispensable resource, just like food and water. Everybody, literally everybody, wants to jump aboard the Wi-Fi bandwagon, and Cisco’s research reveals that by 2023, there will be a whopping 29.3 billion devices connected to IP networks.
Wireless Router Basics 101: For the Absolute Beginner
Most wireless routers have a 2.4 GHz radio band for data transmission. Now, this band consists of several channels – just like the lanes on a highway. The 2.4 GHz has 11 channels in the North American region.
Theoretically, 11 channels should suffice even super populated areas. However, many never really tweak the default wireless router configuration, resulting in many wireless routers transmitting data via the same channel.
This is where a Wi-Fi analyzer app can do wonders for you. In a nutshell, Wi-Fi analyzer tools collect and present key data points from APs (access points) in your network – helping you find ways to accelerate your Wi-Fi speed!

How to use a Wi-Fi Analyzer App – 3 Super Easy Steps
Most Wi-Fi analyzer applications have a scan or survey button which essentially patrols your vicinity and presents many networking related parameters like:
Glance through the results and place heavy emphasis on the Noise and Signal Strength, both measured in dBm (decibel).
High noise levels deteriorate your network signal strength and result in poor connectivity. Electronic devices like cordless phones, Bluetooth devices, etc., can cause noise.
Now, identifying and eliminating noise sources isn’t always straightforward. In fact, increasing signal strength is easier compared to decreasing noise.
Here’s how you can reduce noise:
- Switch your network frequency band from 2.4 GHz to 5 GHz.
- Both the client devices and APs should be 5 GHz enabled.
- If you can’t change the frequency band, try switching APs to different channels as part of the 2.4 GHz band.
- Try switching off electronic devices around you, and register the noise levels in each instance – A/B testing your environment.
- Try moving the APs around and figure out how specific locations impact the noise levels.
And, here’s how you can improve signal strength:
- Eliminating obstructions around the APs is a sure-shot way to improve your signal strength.
- If your network has multiple keys under a WEP security architecture, reconfigure to use just one pass.
- Switch to a different channel.
If you stand right to an AP, your signal strength is probably -30 dBm: which is the maximum possible strength.
Anything down to -50 dBm is a pretty decent signal strength level.
About Channel Selection:
- Wireless networks contain channels within a particular wireless spectrum. Sometimes, a channel gets overcrowded and results in decreased bandwidth or connectivity issues.
- Wi-Fi analyzer tools usually scan through and recommend less-congested channels for your usage.
- The Wi-Fi analyzer is a complete game-changer as you gain access to critical parameters like noise, signal strength, channels, etc. – all of which are paramount to enjoying a seamless internet experience.
- Wi-Fi analyzers differ based on the networking parameters, reporting options, and even supported Wi-Fi standards.
- Some network analyzers have unique features like heat mapping plots and customizable graphs. Now, it’s your turn to decide which Wi-Fi analyzer suits your requirements best.
For instance, certain Wi-Fi analyzer tools pull up information on the channels in your network. As a result, you can seamlessly figure out which channels are less “crowded” and simply switch to that channel.
Don’t stress out just yet. You don’t need to be a networking guru to navigate through a Wi-Fi analyzer. Most tools are user friendly, and you’ll find your way around.
These fields make up your networking parameters like noise, signal strength, and so on. Additionally, a Wi-Fi analyzer adds a layer of analysis instead of merely measuring network performance. As a result, you receive smart recommendations for your AP placement or channel selection.
On the Mac, the native Wireless Diagnostics Tool does the trick:
- Press & hold the ALT key – and also click on the Wi-Fi icon from the status menu.
- Find your network and related connection information like the RSSI.
The RSSI (Received signal strength indicator) networking parameter measures the received signal strength.
